  wall clock time
  
     <software> The elapsed time between when a process starts to
     run and when it is finished.  This is usually longer than the
     processor time consumed by the process because the CPU is
     doing other things besides running the process such as
     running other user and operating system processes or waiting
     for disk or network I/O.
